The invention relates to a rotary transmitter for example for use in machine tools with adjusting tools. The rotary transmitter comprises a stator part ( 18 ) and a rotor part ( 26 ), each having a respective stator core part ( 72 ) and a rotor core part ( 74 ), which are separated from one another at mutually facing ends via an air gap, and each having at least one respective power winding ( 76, 78 ), which is wound on the stator core part and the rotor core part, in order to transmit power using the transformer principle, and having respective stator and rotor coupling turns ( 80', 80'', 82', 82 ''), which are associated with one another in pairs, for inductive data transmission. One aim of the invention is to transmit data without interference. A further aim is a low maintenance requirement. In order to achieve this, the invention primarily proposes that the coupling turns ( 80', 80'', 82', 82 '') are separated from the area of the power winding ( 76, 78 ), and are shielded from them, by parts of the respective core parts ( 72, 74 ), and are arranged in the associated stator part and rotor part ( 18, 26 ) in each case forming a three-dimensioned curved loop.
